* features/Makefile: Generate regformats for mips-linux and

	mips64-linux.
	* features/sort-regs.xsl: Correct typo.
	* regformats/reg-mips.dat, regformats/reg-mips64.dat: Delete.
	* regformats/mips-linux.dat, regformats/mips64-linux.dat: New generated
	files.

	* Makefile.in (clean): Clean new files instead of deleted ones.
	(reg-mips.o, reg-mips.c, reg-mips64.o, reg-mips64.c): Delete.
	(mips-linux.o, mips-linux.c, mips64-linux.o, mips64-linux.c): New
	rules.
	* configure.srv: Specify XML files and new regformats for MIPS and
	MIPS64 GNU/Linux.
	* linux-mips-low.c (mips_num_regs): Set to only used registers.
	(mips_regmap): Do not fetch $0.  Remove unused registers.  Add
	an entry for the restart register.
	(mips_cannot_fetch_register, mips_cannot_store_register)
	(mips_reinsert_addr, mips_fill_fpregset, mips_store_fpregset): Update
	register names to match the XML descriptions.
	(mips_fill_gregset, mips_store_gregset): Likewise.  Handle the
	restart register instead of $0.
